Another Tight One by Habitat

Habitat for Humanity of Martha's Vineyard is really getting the superinsulated, energy efficient home down pat. Last Saturday, accompanied by job super extraordinaire Lee Taberner, I did a final blower door test on the second house they've built at the end of Bailey Park Road. The result - 203 CFM50. Real tight, well under 1 ACH50. Along with this, the HVAC system is a minisplit heat pump, a heat pump water heater, and a heat recovery ventilator.

HfHMV has made the connection between energy efficiency and permanent affordability. So has the Island Housing Trust (South Mountain is currently building two new homes for IHT, also in West Tisbury). It's heartening to see the two most significant affordable housing providers on MV so committed to high performance homes.
